Specification of Letters Patent. I

Patented. Feb. 2?,1906.

Application filed April 13,1905. Serial No. 255,425.

.To all whom it mag concern.-

.fiance, in the county of-Defiance and State of Ohio, have invented new and useful Im rov'e-j ments in Metal Boxes, of which the fol owing is a specification.

This invention relates to improvements in -metal beer-bo'xes of the type set forth in the patent granted to G. Klenk and J L F. Fink on the 24th day -of-December, 1904, No. 778,680..

The object of the present invention is to providespecific structures ,to strengthen the ex and to arrange the parts to economize in them'anufacture of the same.

In'the patent referred to the projection at the'bottom of the boxwas formed by the sections distanced from the sides to form, what was termed'a seat. In actual practice in the, manufacture of the article it "has been found necessary to form a reinforcing element at the corners andto introduce a sepa rate piece to form the projection. By inserting the separate piece the corner is strengthened and a rigid and more substantial'projection is produced. I

' It has developed that -the corner-braces ma be: more expeditiously made and attac ed,*and tothis end a simpler. and more economical brace is provided in the present invention.

The cover as shownyin the prior patent was formed by rolling. the metal around a strengthening element and forming a raised head at the edges. 4 In packing the boxes this raised bead'was found to be objectionable, and'it" formed a place for water to' settle furthermore, the corners were cut off atan' 'angle which formed [an opening and permittedwater which settled in the depression of the cover to run down inside the box. To

overcome these difficulties, the edges are turned over at the top and then. around the reinforcing element to provide a smooth uper surface, and the corners are cut out in the orm of an arc and-bent in such-manner as topermit the ready and convenient bending of the same, and yet cover the uppermost edge of the reinforcing element to revent water runningbetween the same an the bead.

The prime object of the invention is to arrange the sections in such manner thata strong, substantially braced, and neat metal sides is provided.

inafter referred to and 'be out in the claims.

The bottom is'bent at its outer edges the bends 6, 7,'and 8, as shown at 9; The edges of reinforcing-strips 10 are interposed between the bends of the 'sides and bottom, as shown at 11, said reinforcing-strips 10 ex-' tending inwardly a short distance from the which a head is formedto receive a rod 13, to provide a substantial projection at the bottom of the box. v ends of the metal as described produces a strong reinforcing outwardly projecting corner 14 to prevent the box being dented or battered in handling.

The bar :13 is made of a continuous piece the bottom plan view;

' The corners of the sections engage each other and are crimped to produce outwardlyextending' beads 15, which are in a plane with the bottom outwardly-projecting corners 14. These beads reinforce the corners-of the box and at the same'time prevent denting and battering, which mars and frequently distorts the structure and renders it impossible to Fig- 4 is a vertical section.

'\\'ardly from the 'plane of the sectionsflush with the projections 14 and 15.- The metal is extended inwardly from the bottom of'the beads 17 and then bent on itself tofor'm a de-' pressed reinforced flange 18 to receive the cover. A bar 19 is inclosed by the beads17 to reinforce the structure, as will be readily understood. v r The corners of the flange lS- are-mit'ered and connected together by-corner-braces 20, riveted at 21 and providedwithdownwardly extending flan es 22, riveted to the sides and T 1e braces 20 and the reinforced flange 18 make a substantial support for the cover to resistthe strain when the'boxes are piled upon each other'l The cover 5 is made of sheet metal and is flush 'at the top-with the upper ed e of the beads 17, the outer edges being beaded, as at 25,, and inclosing a rod 26. The beads 17 f are bent in from the bottom and the'corners of the cover are cut out in the arc of a circle, so that when the beads are formed the corners of the-rod are covered, as shown in Fig. 7.

This detail of construction serves to prevent: water tricklingbetween the beads and the rod.- The cover is formed with a depression 28, surrounded by a head to reinforce it, and
